Abstract
The paper deals with the assessment of a
surface water quality in the Kherson region, as well as the
assessment of a technogenic load on the surface water
bodies by the volumes of the wastewater and pollutants
discharges over a long period of time. The problem of
supplying the regions of Ukraine with water is urgent for
many regions, including the Kherson region. The
materials from the Regional reports, Ecological passports
on monitoring a state the surface water as well as the data
on the volumes of the sewage and pollutants discharges
were used as baseline data. Water quality indicators was
analyzed using the graphical method of a surface water
quality complex assessment and method of estimation of
surface water quality, based on hydrochemical
parameters. Authors proposed to estimate a level of
technogenic load on the surface water based on the
calculation of the technogenic load module on the water
objects (MWO). The purpose of the work was to assess a
quality of the surface waters of the Kherson region as well
as to assess a level of technogenic load on the surface
water bodies of the region. It is obtained that a surface
water quality of the region according to the fishery
requirements in the most cases is characterized by classes
IVa – IVd, category “very dirty”, by drinking water - class
II, category “polluted”, class IIIa, category “dirty”. There
were significant exceedances of MPC according to
fishery standards in terms of such substances as nitrites,
Cr (VI), Cu and Ni. Maximum excesses were noted for
Cr (VI) content. Also significant exceedances of the
fisheries standards were observed in the content of
sulfates, phosphates, Mn, BOC5, mineralization and
others. In terms of economic and drinking requirements,
the MPC was most often observed in such indicators as
mineralization, BOC5 and Ni.With a general increase in
water intake there is a decrease in the pollutants
discharges. A level of technogenic load on the surface
water bodies has significantly decreased. The obtained
results are a part of a comprehensive study, which are
devoted to the complex assessment of technogenic load
on the surface water bodies of the Northwest Black Sea regions.
